[SOLVED] Zimbra stopped working suddenly, need advice

The server has been running fine for about a year and yesterday it abrubptly stopped working, the admin page and login page just time out. I'm trying to refresh my memory and get caught up on the documentation as well as searching the forums but no luck yet.

You should look in the log files for any errors but, as soxfan suggested, I'd also guess it's the certificates from your highlighted comment.

Also wanted to add a comment about this. Seems like this would be a fairly common problem. I'm a little confused about why this would cause the entire server to fail and then consequently not start up again. The error message you get from zmcontrol and the main logs I check say nothing about a certificate expiring.

Seems like logging could be improved in regards to this, unless I'm missing something.
